If you use https, SOAP modules need to configure with openssl, otherwise will be catch a error like:
SOAP-ERROR: Parsing WSDL: Couldn't load from url
Pré-requis
Cette extension requière l'extension PHP libxml. Ceci signifie que l'option de configuration --enable-libxml est nécessaire bien qu'elle soit implicite sachant que libxml est activée par défaut.

Typically, on microsoft windows(sometimes linux), we got "I/O warning : failed to load external entity" and "Fatal error: Uncaught SoapFault exception: [WSDL] SOAP-ERROR: Parsing WSDL: Couldn't load from somewhere".
only xml lib is not enough, php-soap also need cURL, and openssl if you wants connect to https
